We know that health service is considered as one of the primary infrastructures for development. Even the constitution of Nepal 2072 BS guaranteed the basic health service to all as the fundamental right. Even then many rural communities in Nepal .....
Indeed any nation with honest, labourious and educated people is more developed than others. It is because of the fact that they are fully aware of their rights and responsibilities. They are also aware of the most advanced machines and .....
Effective utilisation of the natural, as well as the available financial resources by qualified human resources, results into development. In the context of Nepal, since Nepal is an agro-based nation the development and modernisation of the sector .....
Nepal is rich in natural resources such as soil, forest, water and scenery. But these resources no matter how much potential they possess can do nothing by themselves for development. They have to be mobilized by skilled human resource. Moreover, .....
Acceleration is defined as the rate of change in velocity. Its SI unit is m .....

Solution : Total surface area TSA = 2 (lb + lh + bh) Volume V = l*b*h Where, l = length , b = breadth or width and h = .....
ANS: As, the effort arm is longer , less effort can easily amplify that effort and become easierto open the lid of the .....
Its true that liquid which do not wet the glass surface form a convex meniscus. A convex meniscus occurs when the particles in the liquid have a stronger attraction to each other than to the material .....
Here, Height of water = h = 6m Density of water = d = 1000kg/m3 g = 10m/s2 We know, Pressure = P = hdg = 6 m x 1000kg/m3 x 10 m /s2 .....

Part 17 article 216 clause 3 and 4 of the constitution of Nepal deals with the formation of the municipal executive. The Municipal Executive consists of one Deputy Mayor, Ward Chairperson elected from each Ward and members elected pursuant under .....
Solution : Let M and m are the two masses and d be the distance between their centres. Then, F = GMm / d2 ........ 1 and, if M = 1/4 M, and, m = 4m, and, d = 1/4 d = d/4 Then, F = G.M/4. 4m / (d2 / 16) = 16. GMm/ d2 So, its gravitational force .....
Solution : Let MP = x Since, discount is absent, So, SP = MP = x SP with VAT = 25425 or, SP + 13% of SP = 25425 or, x + 13/100*x = 25425 or, 113x/100 = 25425 or, x = Rs.22500 and, loss % = 10% loss amount = 10% of CP = 10/100 * CP = .....
When a balloon is inflated, the pressure inside the balloon increases so that the pressure inside the balloon is greater than the pressure outside the balloon (I.e. the air pressure). When we open the balloon, the air is released so the air .....
The weight of the body will become zero during free fall because during free fall the body falls with acceleration equal to accleration due to gravity neglecting air resistance. Hence, the reaction force becomes zero i.e. the force that we .....
